System requirements:

* Microsoft® Windows® Vista, XP, 2000, NT, ME, 98 or 95 * or a UNIX system running X11 (any Linux Distribution, FreeBSD, etc) * or Mac OS X 10.4 or superior (I think Intel Macs only: it doesn't work for me!) * 800x600 or higher screen resolution and at least 16-bit colors recommended * A good display adapter and CPU recommended for smooth performance * Multiple-display systems are supported on Windows 98/ME, Windows NT4/2000/XP * Multiple-display systems are not supported on Windows 95 (Magnifying Glass will be run in the primary display only) * On multiple-display systems, the magnifying glass may not display at the correct location if the monitors have a vertical offset between them.

Q key closes the software * Crosshairs now have tickmarks for scale factors at 4x and above * Variable scale factor from 1x to 32x in * New configuration dialog to choose the plugin, Hotkey and other settings * A list of which features are currently available on the Linux version can be found on the README file distributed with it.
